Abstract

The genera assigned to the family in 1984 (K. Bøvre, p. 288-290, N. R. Krieg and J. G. Holt, ed., , vol. 1) are now recognized as members of two different groups (the beta and gamma groups) of the class . DNA base composition data, findings from DNA-mediated transformation to streptomycin resistance, DNA-DNA hybridization, and DNA-rRNA hybridization, and results from electrophoresis of soluble proteins have revealed differences that mandate separation from of the three species of “false neisseriae” (, and ), and also of the genera , and . Since these organisms must be excluded from the , the new family is proposed to accommodate the genera (including the false neisseriae) and . This arrangement acknowledges the phylogenetic relationships of these organisms and resolves controversies concerning (i) the recommendation that the genus should be divided into the subgenus (for rod-shaped organisms) and the subgenus (for cocci) and (ii) the taxonomic placement of the false neisseriae. The present evidence does not favor inclusion of the genus in the family . The following species are included at this time in the type genus, (the type species), , and . The species allocated at this time to the genus are (the type species) , and .
